To all l'io/10m 'it may concern:

VBe it known that f1, NICOLA DE Riris, a subject of the King of Italy, residing at Binghamton, in the (county lof Broome and State of New York, `-have invented .certain new and useful Improvements in 'Bottle- Neck-Shaping Machines, of which the. following'is va specification,

This 'invention relates :to certain new and useful improvements in "bottle neck shaping machines and has particular reference V'to a manually operable machine .apparatusQfor 'providing `an annular groove in the neck of a bottle while in a semi-plastic state.

Another object of the invention embodies ina bottle neck 'shaping or grooving machine of the type above setforth, the provision of electrically controlled devices Ifor registering the nuinberof bottles sogrooved, such a likable device ibeing rendered operative upon the openingimovement of gripping devices' 'for receiving rthe neck oi? a bottle.

With the above general objects in view and others that will appear as .thenature of the'invention is better understood,'the same consists ofthe novel forni, combination and arrangement of parts hereinafter more fully described, shown in the accompanying draw- :m `ing and claimed. j

In the, drawing, wherein llike reference characters designate corresponding rparts throughout the several views,

Figure 1 is atop plan view of a bottle neck shaping machine constructed in accordance with the `present invention, the gripping jaws for ythe bottle necki being shown in section carried .by 'a shaft supported gear wheel that meshes with a manually reciprocable rack bar to be rotated thereby, and :further `showing the electrical registering devices for indicating the number of bottles so grooved,

Figure 2 is a side elevational view of the machine showing the side bars for the roller supported rack bar and the grippingjaws for the bottle neck,

Figure 3 is a cross sectional view taken on line III-III of Fig. 1 showing the roller mounting for the rack bar,

Figure is a face view of the gripping Jaws Figure 5 is a. fragmentary velevational view, partly vin section showing the gear supporting the sectional gripping jaws "andthe hinge Amounting for said jaws,

Figure l6.is a cross sectional `view taken online VL-VI of Fig 5 showing the itensioned springs for retaining the kjaws in closed position, and

vFigure iis a fragmentary detail sectional view'showingithe gripping Vjawsin open po- Asition against the spring tension .thereon and Aengaging the Contact members ttor v.the electrical registering mechanism.

VReferring more `in detail to the accompanying drawings, Vand.particularly to Fig.

1'1 there is illustrated .a bottle neck shaping lor grooving machine embodying a base yB supported bythe. clamp 'C are carriedby the shaft '5 at a point spaced outwardly of 80 the plate section `1, lsaid jaws being formed of semi-circular `sections forming `a cupshaped or socketed member that are hinged as at 8 to the bracket head 9 fixed tothe shaft 5 asv shown in "F 5. Theyjaw Isections 7 lnormally occupy a closed .position as indicated .in 1 vand r6 by coil springs 10 positioned between the rear ends of said jaw sections and the lbracket head 9. Each jaw section 7 .carries ra handle 11 to facilitate opening movement thereof against 'the tension of the spring 10. Each jaw section 7 is further provided with a spring arm 12 Secured to the inner bottom wall thereof as at 13 and carries upon the inner side adjacent the outer end, a knob or block 14: of metal or stone for forming an externa-l annular groove in the neck of the bottle B upon rotation of the clamping jaw 7. To center or properly position the neck of the bottle in the clamping jaws, an axial pin 15 projects from the end of the shaft 5 and extends into the bottle neck as shown in Fig. 1. The mechanism for rotating the shaft 5 and the clamping jaws 7 associated therewith embodies a rack bar cooperating with the gear wheel 6, there being provided a supporting frame 16 mounted upon the base plate section 1 and carrying spaced horizontal guide arms 17 flared in opposite outwardly directions at one end thereof as at 18, the rack bar 19 carrying roller bearings 2O adjacent each end thereof riding between the guide bars 17 as shown in Figs. 1 to 8 inclusive, while a gripping handle 21 is carried b y the outer end of the rack bar to effect reciprocation thereof. In order to prevent the complete withdrawal of the rack bar 19 from the guide bar 17, the inner terminal tooth 19a of said rack bar is formed of a greater height than the remaining rack teeth for engagement with the gear wheel 6 0 prevent further movement of said rack In the operation of the device, the handle 21 is gripped for reciprocating the rack bar 19 and said rack bar being in mesh with the gear wheel 6 that is fixed to the shaft 5, said shaft is rotated and carries therewith the gripping jaws 7 for the neck of the bottle B. The bottle carried by the clamp support C is moved into the clamping jaws 7 and centered thereby, by the pin 15, the spring arms 12 carrying the sha-ping' knobs 14 engaging the outer face of the bottle neck for forming an annular groove therein upon rotation of the clamping jaws. In removing and placing the neck of a bottle in the clamping jaws 7, said jaws are moved upon their hinge connections 8 with the bracket head 9 of the shaft 5 and when said jaws are open, one of the same cooperates with electrical devices for registering the number of bottles being grooved.

The registering mechanism includes an indicator casing 22 having wired connections with the battery -3 and the spaced contacts Q4. The contacts 24 are disposed ad` jacent one of the hinged clamping jaws 7 and in the path of movement thereof, so that when said jaws are opened, the contact points will be brought into engagement for closing the circuit and numerically increasing the indications upon the register 22.

IVhile there is herein shown and describedl the preferred embodiment of the present invention it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

l/Vhat I claim is 1. In a bottle neck shaping machine, a supporting base plate, a shaft journaled therein, a gear on said shaft, a supporting frame on said base plate including spaced horizontally extending pairs of guide arms positioned at right angles to the axis of said shaft, a rack bar operatively engaging said gear roller bearings carried by said rack bar and projecting between said pairs of guide arms for permitting reciprocation of the rack bar, aliandle on said rack bar for manually operating the same to cause rotation of said shaft, bottle neck clamping jaws carried by said shaft, said clamping jaws being formed of hinged sections carried by said shaft and rotatable therewith, spring devices for normally holding the clamping jaws in a closed position, a spring arm carried by each clamping jaw section, and a shaping' knob carried by the inner face of the outer end of each spring arm for engagement with the external surface of a bottle neck for forming an annular groove therein upon rotation of said shaft.

'2. In a bottle neck shaping machine, a supporting base plate, a shaft journaled therein, a gear on said shaft, a supporting frame on said base including spaced horizontal guide arms extending at right angles to the axis of said shaft, a rack bar operatively engaging said gear reciprocally carried by said supporting frame, a handle on said rack bar for manually operating` the same to cause rotation of said shaft, semicircular bottle neck clamping jaws carried by said shaft, said semi-circular jaws being hingedly connected to said shaft and rota table therewith, said jaws normally forming a cup-shaped member adapted to receive the neck of abottle, spring devices for normally holding said jaws in their cup-shaped formation, a spring arm carried by each clamping jaw section, and a shaping knob carried by the inner face of the outer end of each spring arm for engagement with the external surface of a bottle neck for forming an annular groove therein upon rotation of said shaft.

In testimony whereof I affix my signature.
